Apple was never really that innovative. Their business model was to take recent innovations, like handheld computers, package them up all nice and shiny, and market the hell out of them. That’s what sold the iPod, even though there have been plenty more technically superior devices. Same with all their other products.
But known exploits that have been patched, but not applied because they didn’t update their phone, are plentiful enough.
Update your phones. Reboot them regularly, too.
